Explanation

The chapter explains that the final position P = a + b, where a is the first movement and b is the second movement. Given that the first movement is −4 and the final position is 5, we have: −4 + b = 5. Solving for b: b = 5 − (−4) = 5 + 4 = 9.

Solution Steps

  1. Step 1: Use the formula P = a + b, where P is final position, a is first movement, b is second movement

  2. Step 2: Substitute the given values: 5 = (−4) + b

  3. Step 3: Solve for b: b = 5 − (−4) = 5 + 4 = 9

  4. Step 4: Verify: −4 + 9 = 5 ✓
